The study was conducted to determine whether oak wood vinegar extract influences blood alcohol concentration and hangover syndrome in healthy volunteers. 2% wood vinegar extract was effective to inhibit increase of blood alcohol concentration after alcohol intake and showed significantly different (P<0.1) compared to placebo. By result of questionnaire of volunteers, wood vinegar extract showed effects improving hangover syndrome. In comparative study about blood alcohol concentration and hangover syndrome of wood vinegar extract and other extract that hangover improvement effect was reported, average maximum blood alcohol concentration was lowered in those taking wood vinegar extract than those taking other extract. At drinking completion 210minutes (T210), blood alcohol concentration of those taking wood vinegar extract was the lowest by 0.063% compared with other extract but was not significantly different between in those taking wood vinegar extract and in those taking other extract. However, wood vinegar extract's experimental group was the highest by 0.462 in decrement rate of blood alcohol concentration and, when did P<0.1 by significance level, indicated difference that mean statistically compared to placebo group uniquely. At those taking wood vinegar extract, the improvement rate and the aggravation rate of hangover syndrome was each 87%, 2%. Thus it was concluded that wood vinegar extract showed excellent alcohol oxidation and was effective in hangover improvement.

Alcoholism is a significant health problem in the world. The liver is the first and primary target organ for alcohol metabolism. Alcohol dehydrogenase and aldehyde dehydrogenase play important roles in the metabolism of alcohol and aldehyde. In this study, I aimed to investigate the eliminatory effects of a Phellinus spp. extract on alcohol metabolism in drunken Sprague-Dawley (SD) rats. Male SD rats were given Phellinus spp. extract at 30 min after 40% (5 g/kg) alcohol ingestion. To assay the effect of Phellinus spp. extract on blood alcohol concentration, blood samples were taken from the tail vein at 1, 3 and 5 h after alcohol ingestion. The concentrations of alcohol, alcohol dehydrogenase, and aldehyde dehydrogenase in Phellinus spp. extract treated rat were significantly lower than that of the control with a time-dependent manner. In addition, the alanine aminotransferase and aspartate aminotransferase activities of Phellinus spp. extract-treated groups were altered compared to those of the control group. These results suggest that Phellinus spp. extract intake can have a positive effect on the reduction of alcohol, alcohol dehydrogenase, and aldehyde dehydrogenase concentrations in the blood and may alleviate acute alcohol-induced hepatotoxicity by altering alcohol metabolic enzyme activities. Phellinus spp. extract is thus a good nutraceutical candidate.

Alcoholism is a significant global health problem. Alcohol dehydrogenase and aldehyde dehydrogenase play important roles in the metabolism of alcohol and aldehyde. In this study, we aimed to investigate the eliminatory effects of a fruit extract drink on alcohol metabolism in drunken Sprague-Dawley (SD) rats. Male SD rats were given a fruit extract drink or a commercial product (10 mL/kg) 30 min prior to 40% (5 g/kg) ethanol ingestion. To assay the effect of the fruit extract drink on blood ethanol concentration, blood samples were taken from the saphenous vein at 3 and 5 h after ethanol ingestion. The blood concentrations of alcohol, alcohol dehydrogenase, and aldehyde dehydrogenase were significantly lower in the fruit extract drink group than in the control group, in a time-dependent manner. However, the alanine aminotransferase and aspartate aminotransferase activities of all experimental groups were unaltered compared to those of the control group. These results suggested that fruit extract drink intake can have a positive effect on the reduction of alcohol, alcohol dehydrogenase, and aldehyde dehydrogenase concentrations in the blood and may alleviate acute ethanol-induced hepatotoxicity by altering alcohol metabolic enzyme activities.

We investigated the effects of bean sprouts (Glycine max), dropwort (Oenanthe javanica), and radish (Raphanus sativus var. hortensis for. acanthiformis) extracts on alcohol dehydrogenase (ADH). The extracts from three kinds of vegetables were prepared by extracting with boiling water, distilling water, and ethyl alcohol. Among extracts, boiling water extract showed the highest activating effect on ADH, respectively and distilled water extract had a greater effect on ADH activation than that of alcohol extract. The ADH facilitating effect of bean sprout extract by distilled water was significantly higher than dropwort or radish, hut the effect of the bean sprout extract by ethyl alcohol was lower than others. The facilitating effect on ADH of mixture extracts of bean sprout and dropwort were mixed at 1 : 1 mixture of boiled-water extract showed the highest effectiveness. And bean sprout extract separated below 3000 molecular weight (MW) range of extract fraction had greater ADH activity than large MW parts.

The following results were drawn from the experiment conducted to see the effect of ginseng alcohol extract on the mitochondrial oxidation of the rat liver. 1) Mitochondrial oxygen consumption increased in the low concentration and decreased in the high concentration of ginseng alcohol extract. 2) When the mitochondria was destroyed mechanically or was swollen by low concentration of $AgNO_3$, mitochondrial oxygen consumption was inhibited in all concentration of ginseng alcohol extract. 3) Oxygen consumption of intact mitochondria increased in the low concentration but decreased in the high concentration of sodium deoxycholate. 4) Ginseng alcohol extract inhibited cytochrome oxidase activities of liver mitochondria. These results suggest that low concentration of ginseng alcohol extract activates the oxygen consumption of liver mitochondria by increasing the permeability of the mitochondrial membrane and high concentration of the extract inhibit the oxygen consumption by inhibiting the enzyme activity related to respiration.

Lard 와 Alcohol을 섭취시킨 흰쥐 혈청중의 효소 활성에 인삼추출물이 미치는 영향을 검토하기 위해서 흰쥐에 Lard 와 Alcohol 및 인삼추출물을 첨가한 식이를 10주간 급여하여 성장시킨 후 체중, 각종 장기 중량, 혈청중 AST, ALT, ALP, LDH의 활성을 측정하였을 때 다음과 같은 결과를 얻었다. Lard 와 Alcohol 첨가 식이군에서는 체중과 식이섭취량은 감소하였으나, 인삼추출물의 투여에 의한 식이효율은 증가하였다. lard의 첨가 식이로 성장시킨 실험군에서는 간장, 신장, 비장의 무게는 증가하였으나 다른 식이 군에서의 중량변화는 없었다. 혈청중 AST, ALT, LDH, ALP 활성은 lard , alcohol을 첨가한 식이군(II, III군)에 비해 유의한 감소를 나타내었다. 이상의 실험 결과로 보아 Lard 와 Alcohol의 만성적인 섭취는 실험동물의 간기능에 손상을 유발하여 혈청 중 AST, ALT, ALP, LDH활성이 증가하였으나 인삼추출물을 첨가한 실험군에서는 위와 같은 효소의 활성이 유의적으로 감소하였다. 따라서 인삼추출물은 고지방식이로 인한 고지혈증을 개선함으로써 간조직의 손상을 예방하여 줄것으로 생각되어 진다.

The present study has been undertaken to investigate the effects of crude ginseng extract added to food on the lipid composition in serum of rats fed lard and alcohol. Thirty-five males of Sprague-Dawley strains weighed about 130 g were divided into 7 group, each group receiving a different diet for 10 weeks ; i.e. basal diet plus 15% lard, basal diet plus 5% alcohol, basal diet plus 0.5% crude ginseng extract, basal diet plus 15% lard and 0.5% crude ginseng extract. Determinations were carried out on the net weight gain, food efficiency ratio, weight of organs, triglyceride, total cholesterol, HDL-cholesterol, free cholesterol. The results obtained were as follows : 1. Rats given feed containing lard and alcohol showed significant decrease in net weight gain, but crude ginseng extract caused an increase in food efficiency ratio. 2. Lard supplementation group showed increase in the weight of liver, kidney, spleen, but another groups did not. 3. The contents ratio of triglyceride, total cholesterol in serum of lard-fed group showed significant increase compared to controls and but the simultaneous supplementation of crude ginseng extract and lard decreased significantly than those of lard-fed group. 4. The contents of free-cholesterol and ester cholesterol in serum of the simultaneous supplementation of crude ginseng extract group decreased as compared with the lard single fed group. 5. Crude ginseng extract single-fed groups. 6. The ratio of contents of VLDL, LDL-cholesterol in serum was significantly high in the only lard containing group and alcohol group, the crude ginseng extract supplemented group was showed lower tendency than only lard and alcohol group. The above results suggest that crude ginseng extract would prevent the metabolic disease by improving hyperlipoidemia.
